As show-n on the drawings:

The reference nuneral 1, indicates the walls of a room having a hot water radiator 2, positioned therein einbracing a series of connnu n-icating pipes as shown in Fig. 1. The hyd ro-carbon heating unit embodying the principles of this invention is shown connected with the radiator 2, and coniprises end frames, supports or standards 3, and 4:, spaced opposite to` one another and have rigdly Secured therebetween a gas storage tank or prniary gas reservoir 5, having integrally formed or rigidly secured to the 'bottom t'hereof a fuel nixing or carburetng' pipe 6,-one end of which c0nnnun1- cates with the intorior of the storage tani( 5, and the other end of which is provided with an opening and is disposed opposite the inner surface of the end frame 4-, with the opening therein rogistering With an opening in said end framo. The front wall of the storage tank 5, is provided with a plnrality of alined apertures or openings 7, to afford a primary burnor. Projecting through a suitable aperture in the end frame 4-, and removably threadod into one end of the storage tank 5, is an arni 8, to the outer end of which is rigidly Secured an inclined pipo or auxiliary burner 9, provided with a plurality of burner apertures 10, in the lower surface theroof.

Disposed longitudinally in front of the apertures 7, of the primary burner, and with the ends thereof projecting through and supported by the end frames 3 and 4, is a main or primary oil-gas generating tube or pipo 11, having a spiral spring or coil 12, disposed therein. Reniovably threaded into the end of the main generating pipo which projects .through the end franie 3, is one end of an oil inlet union or Connector 13, the other threaded end of which is adapted to be connected with an oil feed pipo (not shown) but which is connected with an oil supply prossure tank of any suitable type. Mounted longitudinall v in 'front of the storage tank 5, and directly below the main generating pipo 11, is a main wick starting burner 14:.

Romovably threaded into the other end of the main generating pipo 11, is a stub connecting arm 15, which projects through a suitable opening provided for the purpose in the end frame 4, and has integrally formed or rigidly secured at right angles on the outer end thoreof, an inclined auxiliary generating pipo 16, which is closed at its upper end and open at its lower end. The lower open end of the generating pipo 10, is closed by means of a. stopper or plug 17, removably throaded into the open end of said generating pipe 16, to permit cleaning thereof. As clearly shown in Figs. 4 and 6, the inclined generating pipo 16, is disposed below the inclined auxiliary burner 9, and is parallel thereto to permit flames issuing from the apertures 10, to hoat said inclined generating pipo 16, as hereinaftor more fully described.

Integrally formed at right angles near the lower end of the inclined generating pipe, and parallel to and below the stub arm 15, is a nozzle pipo 18, having a passage 19, therein, which comnunicates with a passage 20, in said generating pipo 16, and terminates in an enlarged passage to afiord a seat 21, in said nozzlo pipo. Adjustably threaded into the onlarged portion of the passage 19, of the nozzle pipo, is a threaded shank or screw 22, having integrally formed on one end thereof a valve rod 23, of reduced diameter aii'ording an inclined or taperod portion botween said shank and valve rod adapted to engage against the seat 21. The Valvo rod 23, projects longitudinally through the passage 19, and has its outer end tapered, as denoted by the numeral 24:, to permit the same to seat or project into a tapered oil-gas outlet passage formed in a Valve plug 25, which is renovably threadod into one end of the nozzle pipo 18, thereby affording a suitable oil-gas outlot nozzle or jot which is positioned with the end thereof axially alined and opposite to th opening in the end of the carbureting pipo 6, as shown in Figs. 3 and 13. The other end of the nozzle pipe 18, is provided with an enlarged chamber in which is soated a suitable packing 26, disposed around a valve sten 27, integrally formed on the other end of the shank 22. Said valve stom 27, projects outwardly through a nut cap 28, removably threaded upon the outer end of the nozzle pipo 18, for holding the packing in position. The outer end of the valvo steni 27, is of rectangular cross-section to alford a means for readily adjusting the oil-gas inlet valve mechanism. Securely mounted upon the outer surface of the end frame 4:, and below the auxiliary generating pipo 16, is an auxiliary or socondary wick starting burner comprising a cup or trough 29, having a wick 30, therein.

Integrall formed centrally upon the top wall of the storage tank 5, is a socket 31, having an opening 32, therein. A secondary -burner is removably Secured in the socket 31, and embraces a stand or feed pipe 33, the lower end of which is adapted to rotatably and removably fit into the socket over the opening 32, therein. Formod integrally on the upper end of the feed pipo 33, is a bottom or base plate 3%, having an opening in the center thereof, and a peripheral notch or groove thorein to permit a burner casing 35, to seat upon said base plate. Pivotally mounted upon the base plate 34, to form a valve, is a Shutter or a regulating or controlling disk 36, provided with a handle 37, which extends outwardljr through a suitable slot provided in the burner casing, to af'ford a means for swinging the disk 36, to regulate the flow of oil-gas from the storage tank 5, into the burner casing. As clearly shown in F ig. 8, the top of the burner casing 35, is provided with a plurality of gas apertures or openigs 38.

Secured upon the top wall of the storage tank 5, are supports or brackets 39, upon which are mounted a liquid container or water heater embracing a lower cylindrical hollow casng, hood or tank 40, having one end of an inlet pipo &1, connected therowith, the other end of said inlet pipo 41, being connected with the lowermost tube of the tesa-ao radiator 2, or with any other suitable type of device into which heated water is to be passed. Integrally formed centrally upon the top of the casing 40, is a neck or collar 41 on the upper end of which 'is integrally formed an inverted cup-shaped chambered inner casing or hood 42, of `a diameter greater than that of the casing 40, to permit the inner hood to extend around the upper portion of the casing lO. Projecting through the horizontal portion of the inner hood 42, are a plurality of Vertical tubes 43, which connect the space below the hood with that above the hood. Threaded into an opening ;tormed in the upper centralportion of the top wall of the inner hood 42, is the lower end of a pipe Connector or sleeve Me, upon the upper end of which is threaded an upper or outer inverted oup-shaped casing or hood 4:5, of a diameter greater than that of the inner hood, to pernit the upper hood to surround the inner hood 42. Threaded in an opening` in the center of the top wall of the large upper hood 45, s the lower end of an outlet pipe or tube 4:6, the upper end of which is connect-ed with the uppermost tube of the radiator 2, or to any other suitable type of radiator, 'boiler or hot water reservoir. As clearly shown in Figs. 2 and 3, the water container or hoods are disposed above the secondary or store burner. It will, of course, be understood that any number ofconnected hoods may be provided to permit a liquid to be heated to circulate therethrough.

The operation is as follows:

As shown in Fig. l, the hydro-carbon heating unit is connected with a looped radiat-or 2. To start the heating unit, kerosene or any other suitable hydro-carbon fuel is supplied from a pressure supply tank through the connector 13, into the primary generating pipe 11. The wicks of the primary or main starting burner 14, and of the secondary starting burner 29, are sat`urated with kerosene or alcohol and lighted, the heat resulting from the burning wicks tending to rapidly heat the primary generating pipe ll, and the spring 12, therein, and the inclined pipe 16, thus causing a primary volatilization of the oil within said generating pipes 11 and 16, to form an oilgas, which passes through the inclined generating pipe 16, into the passage 19, of the nozzle, the end of which is disposed opposite the air intake or open end of the carbureting pipe 6. By turning the Valve sten 27, the tapered end 2%, of the valve rod 23, is unseated, thus permitting the generated oil-gas to pass through the restricted outlet passage into the carbureting pipe 6, to be mixed with air which is drawn into the open end ot' said carbureting pipe. The carbu- 'eted air forms a suitable fuel gas which passe s upwardly into the storage tank 5, the

Shutter 36 `being in :closed position to pre- Ventescapeof the oil-,gas into ,the secondary or stove burner The generated oil-gas in the tank', passes outwardly through the apertures 7, forming the primar-y burner, and also passes into the inclined auXiliary burner 9,and out through the burning apertures 10, thereot. The oilgas escaping throughthe apertures 7 and 10, is ignited, the resulting flames from said apertures striking or passing around the respective primary generating pipe ll, and around the secondary generating pipe 16, and the oilgas nozzle mechanisms, thereby Volatilizing the kerosene oil passing into the main generating pipe ll, and the inclined generating pipe 16, to .generate more gas by the burning of the oil-gas already generated by the startingburners 14 and thus permitting the process of oil-gas generation to continue, after being started by the starting burners which, of course, go out after h ohol or kerosene with which .the wicks were saturated has burned up.

After the starting of the device as described, the shutter 3.6, is moved to open position by the handle 37, ,permitting the oil-gas from the storage tank 5, to flow up.- wardly into the burner casing 35, and 'out through the openings 38. The escaping oile gas is lighted, the flames passing upwardly striking against the bottom and around the water tank 40, and into the open spaces af- 'orded between the tani( 4:0, and the inner hood 42, and .between the inner and outer hoods %2 and 4:5. The flames passing into the space .below the inner hood 42, of course, pass upwardly through the short tubes 43, into the space abo e said hood. This arrangement affords a large heating surface for the water container whereby the water within said container -is rapidly heated, the heated water rlslng and passing upwardly through the outlet pipe 4:6, through the radiator tubes and back through the inlet pipe 41, into the heated water container. The heated water circulating through the radiator 2,'heats the same, which in turn radiates its heat to heat the room wherein the radiator is installed.

Due to the novel arrangement of the oilgas generating mechanisms the gas generated therein is heated during its entire passage through the generating pipes 11 and 1-6, and is 'not allowed to cool .ofi` before it is mixed with air in the carbureting pipe 6. This arrangement also preV-ents carbonization of the gas nozzle and gas tip, which are accordingly kept clean and free from clogging. If any foreign substances contained in the kerosene oil are deposited in the nozzleor in the secondary gas generating mechanisms, the respective plugs 25 and 17, may be removed to pe'rmit cleaning of the parts.

It will, ot course, be understood that the chanbered water container supported above the stove burner may have any desired ninnbcr of connnnicating hoods or casings, the shapes of which may be varied to afiord large heating surfaces.
